This reversible cap plastic bottles are the perfect professional packaging solution for your medical cannabis products. They’re made from the highest quality black plastic to make sure your product stays potent and fresh. The caps are the real stars, though, as they feature both a traditional prescription bottle locking top on one side and an easy-open screw top on the other side. You get peace of mind by selling your cannabis in prescription style bottles while your customers can rest easy knowing they can use a screw top if they need to. These 20 dram bottles hold roughly 1.5 ounces of liquid.
